Nitridization, also known as nitriding, is a process which introduces nitrogen in the surface of a material. It is used in metallurgy for surface-hardening treatment of the steel surface. Introduction of nitrogen in the steel is performed at temperatures 500 to 550 °C (930 to 1020 °F) range. Nitriding is altering the composition of the surface like carburization does. In nitridization nitrogen enters the ferrite phase, and the nitridization process does not involve heating into the austenite phase field, thus eliminating the need to quench a part. As a result it provides excellent dimensional control.
Nit Riding Steel with AL
Nit riding steel with AL is used in components requiring maximum Surface hardness of a Nitrided Case combined with fairly High core strength. Parts with small Ruling sections, small bolts, needle beds, parts with thin webs and fine grooves, gauges & precision Measuring tools super heated steam valves.
